MOSCOW, SEPT. 25 -- A former KGB general who recently was elected to the Soviet legislature on the strength of his crusade against the leadership of the secret services has said he helped operate the notorious Walker family spy ring in the U.S. Navy.

Oleg Kalugin told the Leningrad newspaper Rush Hour that he was awarded the prestigious Medal of the Red Star for his part in supervising the Walker family's theft of U.S. secrets. Soviet President Mikhail Gorbachev recently stripped Kalugin of his medals and rank for violating the KGB's code of secrecy, but Kalugin indicated he retained the Red Star.

Kalugin said the Walkers spied for the KGB for 18 years, describing the effect of various nuclear charges and helping the Soviet Union "prepare for an emergency situation."

"Not a single {Soviet} president will be able to take that medal from me," Kalugin said. "I deserved it by right."

The father-and-son team of John and Michael Walker, as well as Jerry Whitworth, were arrested by FBI agents in 1985 on charges of selling codes and other secrets that allowed the Soviet Union access to a variety of information on weapons, contingency plans for nuclear war and ship locations. The elder Walker and Whitworth were sentenced to life terms in jail and the younger Walker to 25 years.

Kalugin, who spied while in the embassy in Washington and then was a high official in counterintelligence here, now represents the Krasnodar region in southern Russia in the Congress of People's Deputies, the supreme Soviet legislative authority. This summer, he has appeared frequently in newspapers and on Soviet television, providing unprecedented information on his former employers.

While he has been embraced by many radical-reformist legislators, some Western intelligence analysts have expressed concern that his revelations could be part of an elaborate deception.

Kalugin said that while he has been stripped of his awards, KGB chief Vladimir Kryuchkov "still retains his privileges," even though 22 high-ranking Soviet intelligence officers have defected to the West during his time in office. Kalugin said that one of the defectors, a personal aide to Kryuchkov, often was sent to the West to buy goods difficult to find in the U.S.S.R. -- "everything from aphrodisiacs for the maintenance, please pardon me, of male sexual potency, to minor things for daily living."

Kalugin also said that despite the nationwide transfer of power from the Communist Party to elected governing bodies, the KGB continues to provide its information to the party and tries to deceive such reformist mayors as Leningrad's Anatoli Sobchak and Moscow's Gavril Popov. He said the KGB and the party also have tried to aggravate food shortages to heighten public tensions and "prompt people toward anarchy and bring on the demand for dictatorship."

The KGB, he added, refuses to give out information on the location of mass graves in cities such as Leningrad and Moscow where the secret police shot countless people during the Stalin era.

"Their lies are detestable since even today, there are special units that every spring go to such cemeteries and cover over the graves again, smooth them over. They cover skulls and bones which protrude after winter," Kalugin said. "If people's deputies or journalists were just allowed to the archives, all the burials could be detected immediately."
